The carbon black, also called carbon black, is a light, loose and extremely fine black powder with very large surface area ranging from 10 to 3000m 2 And/g is the product of incomplete combustion or thermal decomposition of carbonaceous material under conditions of insufficient air. The carbon black reaction furnace is a core device in furnace carbon black production. Different furnace types can produce carbon black varieties with different performances. The carbon black reaction furnace is developed from a single-chamber furnace and a double-chamber furnace to a three-chamber furnace with a throat pipe. The variety, quality, raw oil treatment capacity, carbon black recovery rate and the like of the product are closely related to the furnace type, structure, size, airflow condition, flow rate and the like of the reaction furnace.
The front end of the throat section is connected with the combustion section, and the rear end is connected with the reaction section, so that the front oil discharging gun is far away from the cooling section, the reaction time of raw oil is long, the oil absorption value of the generated carbon black is higher, but the yield is low. The rear oil gun is close to the cooling section, so that the reaction time of raw oil is short, the yield of generated carbon black is high, but the oil absorption value is low, and the product quality requirement cannot be met.
The chinese patent with publication number CN103613959B discloses a carbon black reaction furnace, which increases the yield of carbon black with high oil absorption value by adding a medium-oil-discharging gun in the middle of the throat section, specifically: compared with a rear oil-discharging gun, the medium oil-discharging gun of the throat section is far away from the cooling section, so that the reaction time of raw oil is long, the oil absorption value of the generated carbon black is higher, more carbon black with high oil absorption value can be obtained, and the yield of the carbon black with high oil absorption value produced by the reaction furnace of the embodiment is higher compared with that of the reaction furnace in the related technology.

The different temperatures ensure that carbon black with different particle sizes and controllable proportions is generated in the same reaction furnace due to different particle sizes of carbon black generated by the pyrolysis of the raw oil.
The first method improves the yield of carbon black with high oil absorption value by adding a medium oil gun in the middle part, and the second method realizes that the distance between the second raw material nozzle and the fuel nozzle is different by adjusting the position of the second reaction section, but all the raw materials are conveyed from one side to the inside of the pipeline, so that part of the raw materials are not mixed with energy generated by the combustion section, and part of the raw materials and the energy are lost.
